McCoy Polygonal Barn

The McCoy Polygonal Barn is a historic building located near Hepburn in rural Page County, Iowa, United States. It was built in 1914 as a hog sale barn. The hexagon-shaped building features white horizontal siding, a large monitor with 12 windows, and an aerator. It is only one of five barns known to have been built on a farm in Iowa with a large monitor. Because of this building's original use as a sale barn it was needed to provide the required amount of light. The barn has been listed on the National Register of Historic Places since 1986.
